O2 sensor fault code question
'08 E93, replaced O2 sensor, bank 2 sensor 1. I Cleared that P0050 code and 3 weeks later a new code appears....P112d. Possible "error with O2 sensor (new Bosch), harness open or shorted and( lastly) poor circuit electrical connection." Can I schmear some dialectic grease in the O2 sensor connection to the harness plug? Or could I spray both ends with electrical contact spritz?
Possible bad fuse also? Can I tighten the connection with a zip tie? I know I am rambling but perhaps someone out there had the same error code and found a fix. Pls help if y'all can. Thanx, Mikey |
